It looks like the dynamic loader is failing to find the SSL library
(libssl.so), which is required by your PG client library. I don't know
enough about OSX to know how library searching is handled, but on other
Unixen you'd need to mess with ldconfig or LD_LIBRARY_PATH ... or
perhaps easier, put libssl.so into a more standard location than
wherever it is now.

Alternatively, you could rebuild PG omitting SSL support.
